' 5 Claims. (Cl.4286) This invention relates to strainers and its general object is to provide a straining device that is primarily designed for use .with plumbing fixtures, such as wash bowls, tubs and the'like, and

.for disposal within the drain pipe thereof to .catch and prevent dbris and strands and particles of material from passing down the same and retarding or stopping the flow of water therethrough. V

A further object of the invention is to provide a straining device that includes rotary means caused to rotate by the passage of water through the drain pipe, to catch hair and other strands and particles of material that generally pass through the outlet of the drain and accumulate in the trap thereof, and the straining device including its rotary means isdetachably mounted to allow the removal thereof for cleaning and other purposes.

Another object of the invention is to provide a straining device of the rotary type, that is simple in construction, inexpensive to manufacture, easy to apply and remove and extremely efficient in use, operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a view of my straining device showing the separable parts thereof spaced for the purpose of illustration.

Figure 2 is a sectional view taken through a plumbing fixture and showing my device in use and in elevation.

Figure 3 is a sectional view taken approximately on line 33 of Figure 2, looking in the direction of the arrows.

Figure 4 is a sectional view taken approximately on line 4-4 of Figure 2, looking in the direction of the arrows.

Referring to the drawing in detail, it will be noted that my straining device includes two major parts, one of which may be termed the body, in that it receives the other part for rotation therein. The body includes a ring member I of cylindrical formation, with a cross bar 2 bridging the diameter thereof and disposed at the lower end thereof. Secured to the cross bar and rising from its center is a pin 3 providing a shaft for a purpose which will be presently apparent, and secured to the shaft to rest upon the cross bar is a bearing collar'4 having a convexed upper surface,,as best shown in Figure 3.

The body part is mounted in the drain pipe 5 of a fixture for disposal below the inlet end thereof, to rest upon the usual spider which for distinction is indicated by the letter A, the spider of the form as shown being of the cross bar type and is generally arranged and fixed in the drain 10 pipe of a fixture in the manner as shown in Figure 2.

The body or stationary part of my straining device is removably mounted in the drain pipe, while the rotary part is removably associated 15 with respect to the stationary part, and likewise, includes a ring member 5 of slightly less diameter than the ring member I, to fit within the latter for rotation.

Centrally arranged within the ring member 5 :33 is a tube 6 and radiating from the tube are vanes l, the vanes having their inner ends fixed to the tube and their outer ends to the ring member 5, and it will be noted that the vanes are disposed at a vertical inclination, with notches 8 extend- 5 ing the length of the upper edges thereof, the notches providing teeth, as shown.

While I have illustrated four vanes 1, any number may be employed but in any event the vanes secure the tube centrally of the ring mem- 30 her 5, and they have slots in the lower edges thereof within which are fixed concentrically arranged annular members 9, that cooperate with the vanes in providing compartments to receive and catch the strands and particles of material 35 and prevent the latter from passing down the drain pipe for accumulation therein, as well as the trap thereof.

The rotary member is mounted within the stationary member, by disposing the tube 6 upon the pin 3, and the ring member 5 is of a height and positioned with respect to the ring member to prevent particles of material from contacting the ring member l and retarding the rotation of the rotary part.

It will be obvious that when my straining device is arranged within the drain pipe of a fixture as shown in Figure 2, the passage of water through the device will cause the rotary part to rotate, substantially in the same manner as a turbine, due to the vanes l and the inclined position thereof, consequently strands of hair and material will be received by the vanes and therefore prevent it from passing down the drain pipe. 55

' The rotary part can be easily removed, and the tirety, for cleaning and'other'purposes.

same is true with respect to the device in its en- 'I'he teeth of the vanes will have a tendency to out particles of material into smaller pieces; so as to allow their free passage through the drain pipe. 7

-' It i's thought 'from the "foregoing description 7 f that'the advantages and novelfeatures of my in-' 7 -10 I vention will be readily apparent.

7 I desire it to beunderstood that I may make changes in the construction and in the c'oinbina- ;tion and arrangement of the several parts, pro' V Qvided that such changes fall the appended claims.
